Description:
Low friction and good seal special design 35# automotive Shock Absorber Piston
XIA YI is engaged in developing and manufacturing different kinds of shock absorber pistons,
Powder metallurgy based, with PTFE material banding outside, using a special way to combine them
together. They have advantages of low friction, good seal etc.
The products have passed the Test center, Shanghai Plastic Research Institute. We have testing
machines in our company too and have set up good cooperative relationship with some big shock
absorber factories home and abroad.
Our mass production piston types are: Φ25, Φ27, Φ30, Φ31, Φ32, Φ35, Φ36, Φ40, Φ45......
SPEC: D36XD10X13
